Real-World IoT Use Cases in Automotive Industry
As the applications and benefits of IoT in the automotive industry have expanded, so have the innovations in car manufacturing that leverage IoT. Decades ago, self-driving cars were considered out of reach. Fast forward to today, and not only do we have autopilot and self-driving cars, but also other integrated technologies that make operating a vehicle easier for users.
1. Waymo Self-Driving Cars
Waymo uses a multitude of sophisticated automotive IoT solutions to power its self-driving cars. It is one of the most cutting-edge IoT innovations in the automotive industry. There are 4 main steps for operating the car: perception, localization, planning, and control. Waymo’s IoT sensors are customized for an optimal perception system. They use a combination of cameras, LiDARs, and RADARs.
LiDAR stands for light detection and ranging, and RADAR stands for radio detection and ranging. Both are sensor technologies that can detect objects and measure distances. More specifically, the system is programmed with classifications for different types of cars, objects, and obstacles the car might encounter. Also, Waymo self-driving cars can distinguish whether an object is moving.
2. Tesla’s Autopilot System
Tesla is an example of IoT in electric vehicles. Their autopilot system uses advanced driver-assistance features. More specifically, Tesla has created and implemented a computer vision system called Tesla Vision. It uses a combination of technologies, including ultrasonic sensors and AI vision processing, to enable semi-autonomous driving. When working in tandem, these sensors and processors provide a multitude of benefits for drivers.
The first benefit is lane assistance. Tesla’s automotive IoT integration ensures the car stays in the middle of its lane, improving driver safety. Tesla’s steering wheel also makes automatic steering corrections to make steering and turning more efficient. When on autopilot, Tesla’s system can also detect and respond to stop signs and traffic lights.
3. BMW IoT-Based Solutions
BMW partners with multiple tech companies, including Qualcomm, AWS, Microsoft Azure, and other IoT development platforms to build its technology and manufacturing processes. BMW has created Connected Cars and linked them to the BMW Cloud.
BMW leverages IoT-connected vehicle insights through the My BMW App and ConnectedDrive. These services let users remotely maintain their vehicles and schedule vehicle servicing.
4. Toyota Mobility Service Platform
Toyota’s mobility service platform (MSPF) aims to make driving more accessible and to provide functions for mobility services. It runs in the cloud, and the data gathered by the vehicle is managed by a cloud service developed by Toyota.
By applying IoT analytics for automotive, MSPF transforms vehicle data into insights that improve vehicle performance and enhance overall mobility.
Tips for Building Secure Automotive IoT Applications
When building an application, it is important to understand and implement automotive IoT security. There are multiple risks associated with integrating technology into automobiles, most notably the risk of hacking. If IoT is cloud-based, a hacker can breach the cloud and illegally track the car’s location, unlock doors, or access sensitive driver data.
Connected vehicles rely on constant communication among the car, cloud servers, mobile apps, and backend systems. Multiple connection points increase the system’s vulnerability. Without proper security controls, attackers can exploit weak authentication, outdated firmware, unsecured APIs, or poorly configured networks.
To ensure high-quality security in applications for IoT in the automotive industry, developers and businesses should prioritize protection at all stages of development. The key practices to follow are:
1. End-to-end encryption
All data transmitted between the vehicle, cloud, and mobile app should be encrypted. This way, data will remain unreadable to unauthorized parties.
2. Regular firmware and software updates
Outdated software makes it easier for hackers to find entry points. Over-the-air (OTA) update technologies ensure that security patches can be deployed quickly across all connected vehicles.
3. Network segmentation
It is important to isolate important vehicle systems from less secure components. For example, entertainment systems should be separated from engine controls to limit the damage caused by a breach.
4. Strong authentication and access controls
Multi-factor authentication and role-based permissions should be implemented to limit who can access vehicle systems and sensitive data
5. Continuous monitoring and threat detection
Real-time monitoring allows businesses to detect unusual activity or potential attacks early. Implementing automated alerts and response systems can stop threats before they escalate.
Overall, prioritizing security, anticipation, and proper planning can help ensure the security of automotive IoT. Strong security measures help reduce losses, build customer trust, and increase revenue.
